We show that PAYG pensions can indeed be phased out in a much richer framework where fertility is endogenous and general equilibrium effects are present. Interestingly, the factor that helps us to phase the pension out in a Pareto way is hidden in the structure of PAYG pension itself. Individualistic agents fail to recognize the benefits of their fertility decision on these programs and, therefore, end up in an allocation that is strictly dominated by the allocations that internalize this externality. Exploiting this positive externality, competitive economy can improve its allocations and can reach the planner's steady-state in finite time where each generation secures as much utility as in the competitive equilibrium. Clearly, it is possible to transition in a Pareto way to an economy either with no pension or with pensions whose return is not dominated by market return.</p>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"25 2","pages":"376-406"},"PeriodicalIF":1.1,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41972174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a strategic trade model with endogenous plant location, we study the effect of border carbon adjustments (BCAs) on global welfare and emissions in an emission tax competition game between two asymmetric countries for two games: a simultaneous and a sequential game. Without BCAs, a ruinous “race to the bottom” with no relocation of firms is the only Nash equilibrium in a simultaneous game. In a sequential game, additionally, a “wise chicken” equilibrium may emerge where the Stackelberg leader gives in, letting all his/her plants relocate to avoid being stuck at the bottom. With BCAs, equilibrium emission taxes in both countries are higher, implying lower global emissions and usually higher global welfare in both games. With BCAs, the environmental more concerned country accepts that its firm partially relocates abroad, as it is rewarded with better control of global emissions, tariff revenues and higher net profits (profits minus taxes). This avoids high environmental damages and that either net profits are zero because of high subsidy levels in a “race to the bottom” or because all production plants have moved abroad.</p>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"24 6","pages":"1266-1309"},"PeriodicalIF":1.1,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jpet.12615","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43212825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that the behaviors of individuals participating in a clinical trial differ from individuals not participating. Individuals who are more optimistic toward vaccination participate more in trials. Their behaviors and efforts are also affected.

With efficient rationing and no externalities, the optimal rationed price control exceeds the price at the expected demand–supply intersection if (the numerical value of) the demand slope curve exceeds the supply slope, and is less than this level for the reverse ordering of slopes. If uncertain demand is steeper than deterministic supply, or if uncertain supply is steeper than deterministic demand, expected welfare is greater with the optimal rationed price control than with the optimal quantity control. We obtain, for any specified price level, a partial ranking of the rationed price control and alternative simple price controls. Extending the model to incorporate externalities, we show that, for demand steeper than supply, with a negative externality on either benefit or cost, the optimal rationed price control exceeds the price at the expected intersection of marginal social benefit and marginal social cost; a converse result also obtains.
